any element that is a non metal will do
The single "most likely" element that would form an ionic compound with fluorine is cesium, or possibly francium if enough of it could be collected. This is because cesium, among stable elements, has the lowest electronegativity and fluorine has the highest electronegativity. However, any alkali or alkaline earth metal element in fact readily forms an ionic compound with fluorine, as do many other metals.

It would not be a compound. It is simply fluorine in its elemental form.
If fluorine combines with an element such that their electronegativity difference is more than 1.7, then they will form an ionic compound. Example:- Hydrogen fluoride is an ionic compound. Hydrogen has electronegativity of 2.1 and fluorine has 4.0. So, the difference is 1.9. Therefore, it is an ionic compound.
Sodium fluoride.

Any of the Halogens (Fluorine, Chlorine, Bromine, Iodine, and Astatine) or Noble Gases (Helium, Neon, Argon, Krypton, Xenon, Radon) would be considered a nonmetal.
